older vs newer gte blocks

[jenny89]

I know this has been discussed already but Ive searched the forums and I cant seem to find just how much each block can take. Does anyone know how much power the older blocks without the extra ribbing can handle?

 

[hvyman]

A lot.

What kind of realistic power are you trying to make.

The later block I stronger. There's no info on exactly how much power each motor will take. Too many factors.

 

[jenny89]

Well I just got a 7mgte yesterday with the older block and I have a newer block from a ge. Not sure exactly what I wanna do yet. I guess id like to eventually make around 600 hp but thats a long way off

 

[hvyman]

Either block is strong enough for that. The gte has the added piston squirters tho.

 

[maxburn]

Pretty sure the only differences between the two are the oil squirters and oil return/feed for the turbo on the gte. Are you planning on running forged internals or what are you planning for the build?

Seems to me I have read in older post the newer block can be bored larger than the older block. Have never heard of overall strength issues
with either regarding Horsepower(assuming equal internals used).

 

[hvyman]

Don't want to go more than 40 over on either block. Plus that would require custom pistons.

The newer blocks are about 2mm thicker all around. But the space between cylinders is the same.

 

[maxburn]

If it were me I'd just go with the older block since it already has the oil squirters etc. With 600 hp I don't think you'll have to worry about the added 2mm

 

[jenny89]

Actually the one I got is a jdm without the oil squirters

 

[jenny89]

And thanks for the feedback everyone

 

[maxburn]

Did the jdm come with oil feed/return lines? If it didn't I can't see any reason for not using the ge block as they would essentially be the exact same with the late block slightly edging it out with its slight added strength

 

[jenny89]

Yea the feed/return ports are the only differences except for the extra ribs on the ge. I could use the ge if I had it drilled but if the gte can handle the power ok I might as well use it

 

[jenny89]

How big of a difference will lack of oil squirters make? I know ill have better oil pressure but idk how essential the squirters are

 

[maxburn]

That's the way I would go to with the gte less machine work the cheaper haha

 

[jenny89]

Yea lol I like cheaper as long as it doesnt affect reliability

 

[hvyman]

The squirters help with keeping the pistons cool. There a good thing. Most turbo engines have them.

But there has been number opus high hp 7m that have had them blocked off with forged pistons.

 

[jenny89]

I guess it just bothers me that its not the best possible block lol. Not that theres anything wrong with it

 

[jenny89]

Im definitely planning upgraded pistons and rods. So I should be ok without the squirters? Still good reliability? I wanna build it for the street

 

[maxburn]

Yeah You'll be good on reliability with forged pistons and rods as long as the block is decked and head is milled for MHG. After that the most important thing for reliability is a solid tune and maintenance.

 

[jenny89]

Yea im gonna tear it down soon and have it checked. Its already been machined and mhg installed by the person who imported it so ill have to see how much thicker gasket ill need after its machined again
